About Us
In simple terms, our AIM is to "value add" through Availability, Innovation & Maintainability improvements,
I
incorporating wear, safety, access & flow analysis to deliver overall plant efficiency.
Our "Transfer A & M Solutions" are focused on providing innovative concepts which incorporate operational
I
benefits of safe access (minimising confined space entry) reduced wear consumables usage, maximise
I
product throughput and ensuring even delivery of product to the receiving conveyors.

"WAMS Slams Maintenance Costs"
A

company
claiming
to offer
a unique
equipment
liner
maintenance
and
supply
service
has
impressed
several
major
mines
...
WAMS Customer Base
We are focused on the high wear issues of the hard rock metaliferrous Mining Industry, comprising of -
I
Gold, Copper, Lead, Zinc, Nickel and Iron Ore operations.
Major customers include Rio Tinto, BHP Billiton, Newcrest and Xstrata.
Successful
Case
Studies
Wear/Shutdown Frequency -
Case Study, BHP Billiton Newman "CV214 to CV216" Transfer
Before:
The original
installation
was an
impact face
and spoon
discharge
chute system
using white
iron blocks
for wear
protection.
Issues:
This
installation
suffered
severe liner
wear leading
to a 2.5
week
inspection/repair
regime.
This
transfer
also
experienced
Regular
chute
“blowouts”
and the wear
rates that
were not in
line with
shutdown
regimes thus
leading to
reactive
maintenance.
After:
The
original
transfer
was
replaced
with
a
WAMS
WEarBAck
“Liner
Less”
chute
system
Benefits:
The
severe
liner
wear
has
been
eliminated
with
ledge
liner
life
now
out
to
approx
10
months.
This
transfer
(together
with
CV216
to
CV218)
are
no
longer
the
drivers
for
plant
shutdowns.
Chute
blowouts
have
also
been
eliminated
thus
taking
away
the
need
for
unplanned
reactive
maintenance.

Conveyor wear – Case Study, Newcrest Telfer Operation “Pebble Stockpile Discharge”
Before:
The
original
installation
was a
direct
stockpile
load
discharge
system
on to
the
outgoing
conveyor.
Issues:
The
outgoing
conveyor
experienced
severe
belt
wear on
both the
top and
bottom
covers
leading
to 2
belt
changes
per
annum.
The
outgoing
conveyor
also
experienced
high
conveyor
power
draw
(AVE
125amps)
at all
times
and
counterweight
bounce.
Output
was
regulated
by a
narrow
discharge
opening
which
was
difficult
to
control
and lead
to
difficulties
achieving
the
required
throughputs.
After:
The
original
installation
was
replaced
with
a
WAMS
WEarBAck
“Liner
Less”
chute
insert
system.
Benefits:
The
outgoing
conveyor
wear
has
almost
been
eliminated.
The
outgoing
conveyor
power
draw
is
significantly
reduced
(AVE
55amps)
and
counterweight
bounce
eliminated.
Output
is
now
more
constant
and
throughputs
can
be
controlled
and
achieved
via
the
VSD.

Conveyor
wear/belt
tracking
–
Case
Study,
Newcrest
Ridgeway
Operation
“Portal
to
Stacker
Transfer”
Before:
The previous installation was an impact plate and rock box spill tray style transfer, using white iron lip & wall liners.
Issues:
The outgoing conveyor experienced significant top cover wear due to the high impacts from dropping ore. The outgoing conveyor also experienced tracking issues when in the waste stockpile position due to off centre belt loading.
The previous installation had a 6 week maintenance frequency for liner changes.
After:
The
original
chute
was
replaced
with a
WAMS
WEarBAck
“Liner
Less”
chute
system
Benefits:
The
outgoing
conveyor
top
cover
wear has
been
reduced
as the
ore is
now softly
loaded
onto the
outgoing
conveyor.
The
installation
of the
WEarBAck
design
has
eliminated
the
tracking
issues
as the
belt is
centrally
loaded
in all
positions.
The new
installation
now has
a 20
week
maintenance
frequency
to
replace
ledge
liners.

Skirting wear/poor access – Case Study, Newcrest Cadia Operation “CH614 Screen Discharge Chute”
Before:
The chute installed previously was a conventional rock box lip lined discharge transfer, using white iron lip & side liners.
Issues:
This installation experienced significant skirting wear due to the offset discharge on to the outgoing conveyor.
The original chute had poor maintenance access to the discharge opening. This lead to a significant risk of manual handling injuries.
The outgoing conveyor suffered tracking issues due to off centre loading from the discharge of the original chute.
After:
The original chute was replaced with a WAMS WEarBAck “Liner Less” chute system
Benefits:
The outgoing conveyor skirting wear has almost been eliminated.
A removable top cover and front door were incorporated into the WEarBAck design ensuring easy access for maintenance and reduced risk of manual handling injuries.
The WEarBAck design centralised the load on to the out going conveyor thus eliminating tracking issues.

Poor
Maintenance access –
Case Study, Pilbara Iron Cape Lambert “SFP 187 Skirting”
Before:
The original skirting
installation was a fixed steel skirt plate system with a cumbersome dust sealing mechanism and minimal liner
adjustment.
Issues:
This skirting system
suffered poor maintenance access leading to significant safety
issues (confined space), and a high risk of manual handling injuries.
The poor access leads to down line
effects such as belt damage due to difficulties carrying out
routine maintenance (skirt liners difficult to adjust)
After:
The original
installation was replaced with a WAMskirt modular skirting
system which can be fully maintained externally.
Benefits:
This installation
now provides full external access thus eliminating confined
space requirements.
The lighter
components in the WAMskirt system minimises the risk of
manual handling injuries.
The WAMskirt system provides
quick liner replacement, thus reducing
maintenance durations and freeing up resources for other
areas.
